ETS1EY MCCB
ETS1EY MCCB (Moulded Case Circuit Breaker) is a high-capacity circuit protection device designed for industrial and high-demand residential applications. It provides reliable protection against overloads and short circuits, and can also function as a main switch or isolator. With a rated current range of 100A to 800A and a breaking capacity between 10kA and 35kA, MCCBs are ideal for systems where standard MCBs are insufficient. They are commonly used in main distribution boards, capacitor banks, generators, and primary power feeders.
Manufacturer: OEM
Standards: IEC/EN 60947-2
Rated Current: 100–800A
